Summary: The study investigated the suitability of a denitrifying Moving Bed Bioreactor (MBBR) as a low footprint technology and found that it can achieve removal efficiencies of not less than 90% under optimal conditions, even when operating at low temperatures. While the full-scale MBBR showed slightly lower removal efficiency, by intensifying mixing, improved results were obtained.

Summary: The ditch systems in Northeast Arkansas play a crucial role in managing water quality, with vegetation coverage impacting the water quality. Sites with greater vegetation coverage have lower loading values. Water quality parameters are often higher in the non-production season compared to the production season, indicating a need for additional control measures during this time. This study provides insights into the important processes that can potentially improve regional water quality.

Summary: A growing number of farmers' cooperatives cultivate crops without chemical pesticides, but also without organic certification. This intermediate form of agriculture between conventional and organic production can contribute to a successful transition towards more sustainable agricultural systems. The research findings from the AgroBioDiv project on the farmers' cooperative KraichgauKorn in Germany suggest that while the biodiversity on KGK cereal fields is higher than conventional fields, it is lower than organic fields. This model also shows a higher presence of endangered wild species on KGK fields compared to conventional fields.

Summary: Organic pesticides are significant sources of soil pollution in agricultural lands, and their accumulation in human bodies is concerning. In this study, the presence of 18 pesticides in natural soil samples from agricultural lands was investigated, revealing the effectiveness of photocatalytic degradation using TiO2 or ZnO photocatalysts under UV radiation. The results showed that the five most abundant pesticides could be completely degraded within 20-24 hours using these photocatalysts, with TiO2 demonstrating higher activity. Notably, the persistent and toxic organochlorine pesticide heptachlor was completely degraded within 30 hours for the first time in soil using TiO2 photocatalyst.

Summary: This study assessed the levels, compositions, and distribution of 33 organochlorine pesticides (OCPs) in Greek agricultural soils. DDTs were found to be the major compounds, with the highest concentration. Most samples did not exceed the target values for DDTs, except for one sample from Aegina Island. The majority of analytes had lower concentrations compared to the predicted environmental concentrations, except for the DDE metabolite.

Summary: Meeting the nutritional needs of a rapidly growing global society is challenging due to weed species, which are the main limitation to agricultural production. The use of traditional herbicides is not sustainable, making bioherbicides a promising alternative. Despite the effectiveness of microbial bioherbicides, the market for these products is still relatively small.

Summary: Comprehensive monitoring of air and soil in Oman was conducted to understand the sources and fate of organochlorine pesticides. The study found DDTs in agricultural soil samples with a wide range of concentrations and highest levels at locations with intensive agricultural practices. Among the newly enlisted POPs, pentachlorobenzene was detected most frequently in both air and soil samples. The study indicates volatilization processes from soil and the potential cleansing effect of oceanic air on atmospheric OCP levels.

Summary: This study characterized pesticide exposure to aquatic communities by analyzing streamwater samples from agricultural areas in southwestern Ontario, Canada. Various pesticides were detected in the samples, including herbicides and neonicotinoid insecticides. The study found associations between pesticide concentrations and upstream land use and crop type, and overall low potential toxicity to aquatic communities. However, certain pesticides may pose a toxicity risk to aquatic invertebrates.

Summary: Global agricultural development programs have been successful in reducing greenhouse gas emissions, especially through forest management and promotion of improved agroforestry systems. Improved crop management and grassland management also contribute significantly to emissions reduction. However, the impact of soil organic carbon sequestration needs to be carefully interpreted. In order to achieve emission reduction goals and ensure food security, global agriculture development programs should prioritize the development and implementation of agricultural policies.

Summary: A study in an important agricultural area in Cordoba province, Argentina, found high detection frequencies of urinary metabolites of organophosphate and pyrethroid pesticides among residents. Negative associations were observed between the concentrations of certain metabolites and Er-AChE activity, suggesting potential health effects at exposure levels below ADIs. The study also highlighted the presence of metabolites of pyrethroid pesticides in all samples, with significant negative correlations with Er-AChE, indicating effects on the acetylcholine system.

Summary: This study compares residential proximity to agricultural land using a groundtruth approach and commonly-used satellite-based estimates. It finds that the estimates from satellite-derived datasets are likely to result in exposure misclassification. The study proposes a novel approach that combines different sources of satellite imagery to improve the accuracy of agricultural proximity estimation.

Summary: This study focuses on enclosed or semi-enclosed basins where wind is the dominant driver of water surface tilting, leading to wind tides that contribute to water level rise. The research used the 1-D steady form of the depth-averaged shallow water momentum equation to study wind-induced free surface tilting. Observations at two field sites showed non-linear but symmetric patterns of wind tide behaviors, with higher wind speeds resulting in steeper surface slopes. Traditional wind-dependent drag coefficients provided better predictions in very strong wind conditions but had limitations in shallower basins, suggesting the need for considering other physical parameters for drag coefficient parameterization.

Summary: The Morcille catchment in the Beaujolais region of France is a sub-catchment of the Ardieres catchment where research on surface water contamination by pesticides has been conducted since 2002. A comprehensive dataset combining hydrological, chemical, ecotoxicological, and ecological impact data has been established, showing spatial and temporal variability in water quality associated with pesticide use and rainfall patterns. The monitoring data also indicated the effectiveness of vegetative filter strips in reducing pesticide fluxes in surface runoff and infiltration water.

Summary: Understanding the spatio-temporal dynamics of glass eel recruitment is crucial for assessing eel population status and future stock. In this study, a Bayesian State-Space Model was used to investigate the temporal variations in glass eel recruitment in the Rhone delta (France). The results showed inter-annual variations in recruitment with no specific trend, as well as substantial spatial variations in the resulting recruitment. The findings highlight the importance of accounting for spatial heterogeneity in the dynamics of glass eel recruitment.

Summary: The present study focused on characterizing soil water extractable organic matter (WEOM) in the Doukkala zone of Morocco. By using UV-Visible absorption and 3D fluorescence with PARAFAC chemometric analysis, the study revealed the presence of terrigenous organic materials with some biological components in the soil. The results also showed that these materials are in similar stages of humification with an important humic character. Furthermore, the study found that the fulvic acids fraction is prevalent in the humic material of the organic matter.

Summary: The search and identification of organic contaminants in agricultural watersheds is crucial for understanding watershed contamination by pesticides. Recent advances in analytical strategies, such as non-target and suspect screening analysis, have provided a more comprehensive view of watershed contamination. However, the lack of analytical standards and suspect databases for unknowns, such as pesticide transformation products, limits the scope of suspect screening analysis to known molecules.
